:crazy: Im totally lost. I've spent the last two weeks reading posts and every time I think I got it figured out I don't. In 2012 I put a coolrunner rev A in the trinity I have. RGH'd it successfully and no issues for 2 years. Then came Demon. Installed that and was able to get both sides to boot. I have to add that I did all this following Tutorials and with very little understanding of the concepts behind what a nand is and ecc etc. You don't have to add that I should have had a professional do this, I've seen enough posts with that added. I was fine until I tried to update the retail side on M$ Live and the power in the house went out during the update. After that both sides would give me a red light after approx 20-25 seconds. I have since been able to rebuild an image to the Demon side and it boots to Xell and Freestyle. I am stuck at this point. I would hand over my box to a professional right now if I knew of any in my area, just to save the hassle. However, I find this really interesting and am learning alot. I thought the soldering would be the hard part, no way. Is there a way to find out if my stock nand is still good. I used Multi-builder to build the original RGH and still have the CPU and nanddump.bin from that. I used J-runner to program everything now. I tried to flash the nanddump.bin to the retail side with no results. Do I need to build a retail image with my original dash with xebuild before flashing? Sorry, feel like an idiot here. If I have the steps to follow then I will post logs and pics of the instal if you want, however, I don't think the install is the issue (not that I would know).
